Abstract
Thiosalts contained in waste streams are oxidized to sulfate ions in the presence of sulfur-bound copper. Air oxidation of the waste stream is effected in a slurry of the copper compound, which may be CuS, Cu.sub.2 S or chalcopyrite, and continuous long term operation is possible without loss of catalytic activity and without catalyst degradation.
